Evaluations of mechanical complications related to CVP of the chest wall using FCS performed via the subclavian vein have been reported. However, the delayed complications of a CVP placed in the upper arm have not been sufficiently evaluated in a large population. We evaluated the effectiveness of FCS of CVPs implanted following percutaneous cannulation of the subclavian (chest wall group) or brachial (upper arm group) vein.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>A CVP was implanted in patients with advanced cancer requiring chemotherapy.

FCS was performed in 26\/390 (6.7%) patients in the upper arm group and 40\/800 (5.0%) patients in the chest wall group. The clinical characteristics of the patients were similar in both groups. The duration of CVP implantation until FCS was significantly shorter in the upper arm group (136 \u00b1 96.6 vs. 284 \u00b1 260, <jats:italic>p<\/jats:italic> = 0.022). After FCS, the incidence of CVP removal\/reimplantation being deemed unnecessary was higher in the upper arm group (21\/26 [80.8%] vs. 26\/40 [65.0%], <jats:italic>p<\/jats:italic> = 0.27). In the upper arm group, no cases of catheter kinking or catheter-related injury were observed, and the incidence of temporary obstruction because of blood clots that could be continued using CVP was significantly higher than that in the chest wall group (10\/26 [38.5%] vs. 4\/40 [10.0%], <jats:italic>p<\/jats:italic> = 0.012).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>FCS was effective in evaluating CVP system-related mechanical complications and deciding whether removal and reimplantation were required in both groups.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12957-022-02565-7","type":"journal-article","created":{"date-parts":[[2022,3,22]],"date-time":"2022-03-22T08:02:35Z","timestamp":1647936155000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Effectiveness of a flow confirmation study of a central venous port of the upper arm versus the chest wall in patients with suspected system-related mechanical complications"],"prefix":"10.1186","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1014-2833","authenticated-orcid":false,"given":"Hiroyuki","family":"Tokue","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Azusa","family":"Tokue","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshito","family":"Tsushima","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2022,3,22]]},"reference":[{"key":"2565_CR1","first-page":"706","volume":"92","author":"JE Niederhuber","year":"1982","unstructured":"Niederhuber JE, Ensminger W, Gyves JW, Liepman M, Doan K, Cozzi E.
